Floors

Located in the above-ground floors of Old Main were the administrative offices, faculty offices, class rooms, lectures halls, and at one time even a natural history museum. To take a virtual tour of what the Third floor of Old Main would have looked like, please visit out 3D Virtual Tour developed by former intern Dave Watt (2012).

The Third Floor: ISNU Debate Societies

The Philadelphian Debate Society, originally named the Normal Debating Society, was the first ISNU debate society established four days after the university opened in 1857. In 1858, a rift among members led to the establishment of a competing society called the Wrightonian Debate Society. Both societies were given rooms adjacent to one another on the third floor of Old Main, named the Philadelphian and Wrightonian Halls, where members met and conducted society business until the condemning and subsequent removal of the third Floor in 1946.
